Specification of Letters Patent. Patented Feb. 29, 1916.

Application filed November 13, 1914. Serial No. 871,973.

To all whom it may concern: 7

Be it known that we, JAMES F. PETERS and JAMES WV. DUDGEON, citizens of the United States, residing at Latrobe, Westmoreland county, Pennsylvania, and Pittsburgh, county of: Allegheny, Pennsylvania, respectively, have invented certain new and useful Improvements in Shoes, of Whichthe following is a specification.

This invention relates to a shoe sole.

In steel works, glass factories, rolling mills, tin mills, hoop mills, and other places where men are compelled towork on hot floors of iron, brick or concrete, the ordinary soles of shoes do not exclude the heat from the wearers feet. Moreover, at the present time, men working in the places mentioned wear a sole of leather of comparatively great thickness and which is studded with numerous steel studs. The result is a very heavy and expensive sole and one which is not fireproof and is anything but comfortable.

It is, therefore, one object of our invention to provide an auxiliary light, fireproof sole for shoes which is formed in a mold, or otherwise shaped to fit on and be secured to the wearing surface of the regular sole of a shoe, and which is so constructed as to provide for the passage of an air current between the regular sole and the auxiliary sole under steppingaction of the wearer.

Another object is to provide an auxiliary fireproof sole for shoes which is so constructed and formed that it may be part of a new shoe or be readily secured to the regular soles of shoes and which is so formed as to provide an air cushion between the regular and auxiliary soles, allowing a current of air to pass between the regular and the auxiliary soles under walking action of the wearer.

A still further object is to provide a shoe sole composed of asbestos metallic cloth impregnated with a water-proof preparation.

With the above and other objects in view, the present invention consists in the combination and arrangement of parts hereinafter more fully described, illustrated in the accompanying drawings and particu-. larly pointed out in the appended claims, it being understood that changes may be made in the form, proportion, size and minor details without departing from the spirlt or sacrificing any of the advantages of the invention.

In the drawings: Figure 1 illustrates a regular heel removed and illustrating our improved auxiliary sole in section, applied thereto.

Fig. 2 is a top plan View of the auxiliary sole. F1g. 3 is a transverse sectional view on the line ma2 of Fig. 2.

Referring now more particularly to the.

.side view of an ordinary shoe with the at 6 and includes a heel portion 7. This auxiliary sole is preferably composed of fire-proof material such, for instance, as asbestos metallic cloth impregnated with a water-proof preparation and may be made in different thicknesses. It may be formed into the desired shape in any suitable manner, one way being to formthe same in a mold. This auxiliary sole 6 may be nailed to the regular sole 5 by first removing the ordinary heel, if the shoe be provided with the latter. The means for securing the auxiliary sole to the regular sole of the shoe may be carried out in any other suitable manner.

The auxiliary sole is provided with a clepression a which is bounded by the marginal front and rear pairs of ribs 8 and 9, respectively. Each rib has its ends spaced from the ends of adjacent ribs so as to provide an air passage 10 at the heel portion, air passages 11 on opposite sides of the sole, and an inlet passage 12 for air at the front of the sole. The ends of the ribs are preferably beveled to give the air passages a flaring formation, as shown. If desired a centrally disposed longitudinal rib 13 may be employed.

By virtue of the auxiliary sole being composed of asbestos metallic cloth impregnated with awater-proof P eparation, it is rather hard and dense but possesses suificient yieldability under the action of the wearer, and by virtue of the ribs 8 and 9, the depression at forms an air space providing a cushion between the auxiliary and regular soles andthrough which air cushion passes currents of air under the stepp ng actlon of the wearer.

.It will be understood that'we may manu- 'facture shoes complete for the trade or that We may manufacture our auxiliary soles for application to ordinary shoes- When shoes are worn in alkali, cement,

chemical, acid, furnace, oil, gas, coal or like works or plants, the depression a, and also" the rib 13 may remain but it ispreferable' that the air passages 10, 11, and'l2 be closed:

and this may be done by forming a 0011- .tinuous rib in lieu of theribsFS and 9, for

in such places there are liquids to contend with and not heat.

cWhat isclaiined is: i

in a shoe, the combination with an upper and-a soleyof an auxiliary sole composed of fire resisting and acid proof material secured to the first named sole and sole in spaced relation to the aforesaid ribs.

2. In a shoe, the combination with an up- .periand a sole. ofa relatively stiff auxiliary sole composed of fire resisting and acid proofniaterial secured to the aforesaid sole, the auxiliary sole hav ng spaced ribsalong ,theedgespf its upper face to form a depression andfprovide an air cushion between the soles, the spaces between the ribs be ng arrangedat the toe and heel portions [or the auxiliary sole and at the instep portion thereof whereby air passes back and forth through said passages into and out of thedepression formed between the main and auxiliary soles. V s

3; A fire reslstingand acid proof shoe sole having its inner face provided wlth ribs along its edges .to',;form afd'epression onthe inner face of the sole, the ribs having their ends spaced from one another topicvide passages at the. .toe .and heel po-rtions and at the instep portion of .the sole, the

latter passages permitting a slight trans verse bending of thesole under the walking action of .the wearer.

In testimonv whereof, I hereunto aflix my signature in .the presence of two witnesses.
